Formula: Net value of fund units = (total assets-total liabilities)/total number of fund units.
There are differences in transaction prices between open-end funds and closed-end funds:
1. The subscription and redemption of open-end funds are based on the net asset value price of the unit fund on the current day, which has not been known at the time of trading, but it can be calculated after the market closes on the current day and announced on the next trading day.
2. The transaction price of closed-end funds is the known market price at the time of trading.
